More info

TTA-500 is 2 x 35W Class AB high fidelity vacuum tube integrated amplifier utilizing four EL34 tubes in the output stage and a 12AX7 tube preamp section, composed of two 6SN7 tubes as drivers, and a Triode / Pentode mode selector switch.


TTA-500 uses audiophile-grade coupling capacitors: Wima  for input and connecting driver tubes with the output amp, and Rubycon capacitors in the power filtering.

The amplifier sounds in a very warm, lifelike way and high dynamics and the sound is very linear with almost no negative feedback.

High-quality  EI broadband sound output transformer provides voltage stability and constant and immediately-available energy at any volume level. The both channels use independent rectifier and filter circuits in the supply power. The sound is natural and fresh with deep multidimensional soundstage.

The audiophile grade  ALPS volume potentiometer ensures minimal noises and channels crosstalk and has excellent operational feel and limits errors between the two channels.

The high-end class, gold-plated speaker terminals offer almost lossless audio signal transmission to speakers.

Analog inputs with high-end solid machined brass RCA sockets can accommodate up to 3 stereo devices.

The preamplifier input (HT input) is dedicated for using the TTA-500 as a tube power amplifier and allows to connect it to your Home Theatre system (AV receiver or amp) to drive front left and right channels - now you can use the same pair of speakers in your high-end stereo  as well as in the multichannel system without switching speaker cables nor changing the amplifier.

The removable IEC power cable gives you an option to upgrade your system with a premium audiophile power cable in any time.

The TTA-500 amplifier does not only sound great but it also looks magnificently. The front and side walls of the housing are made of thick 6 mm aluminum. The vacuum tube decorative panel is finished in a modern brushed aluminum color.


Enjoy the analog sound at its best – Enjoy the TTA-500!

The TTA-500 with the standard tubes onboard is characterized by excellent control of the low frequency range in both modes – triode and pentode. Of course the triode mode requires speakers with slightly higher sensitivity but if we satisfy this condition then the amplifier will pay back with the splendid rhythm in the bass range.
Based on this fact we can tell that not only the amplifier’s tube output stages are well built in terms of current efficiency but that it also has an efficient power supply which provides a big power reserve much beyond the nominal demand of the output tubes.
Thanks to good control of the bass and decent dynamics the TTA-500 feels good in music which demands very vivid presentation and especially fast attack, mostly in the macro scale. If you are fans of rock, metal or even music from the dance floors then this tube integrated amp will give you a lot of joy in playing such music genres.
As befits tube amplification Taga Harmony TTA-500 offers nice, juicy and most of all open mids that is why when you want to fully use its potential, especially in the classical or jazz music, then I recommend to match it with speakers which provide rich details in the mid frequencies including the newest Taga Harmony models from the Platinum series (I had an opportunity to personally work on their sound)….”

Taga Harmony TTA-500 presents such a complete and most of all consistent sound that I can admit with a clear conscience it is one of the best tube constructions I have ever had a chance to meet with in this price level.
And what distinguishes this amplifier?...
The manufacturer has not invested in optional, trendy features and put the money which was “saved” in that way in fine tuning of circuits which have a direct impact on a sound.


The result is that the TTA-500 sounds like a pure valve amplifier and besides it offers the triode mode which will be definitely used by owners of high-efficiency loudspeakers. And it does not cost a fortune so the solid tube technology is almost available at your fingertips.”

"... each of the four tested devices (prices between 1700.- - 12.000 Euro) has its own character, but each provided a lot of fun in their own way what I have not seen for a long time. That also applies to the most affordable TAGA amplifier (about 1700.- Euro)!”


The TAGA TTA-500 is a thoroughly attractive device for connoisseurs and newcomers to the world of tube amplifiers. CLEAR RECOMMENDATION!“
